"Show result" button does nothing when 3D is enabled

[MaximeMaW]

After processing a 3D image with ANNA-PALM, I have the possibility to view it in 3D, as the "show result" switch appears. However, this switch does not update the 3D view. My guess is that this happens because the processing is only performed in 2D, so there is nothing to display in 3D. Thus, I find this switch a little bit misleading. Could it be removed/greyed when the 3D view is enabled?

Many thanks for this great code!
